So much classical music happens in the summer here, it’s easy to miss the good stuff. And for people who like their music contemporary and star-studded, the joint appearance of string giants Joshua Bell and Edgar Meyer at the Aspen Music Fest Saturday night is one of the more exciting events of the season.

The violinist (Bell) and the bassist (Meyer) will perform Meyer’s own Concerto for Violin and Double Bass with the Aspen Chamber Symphony. This duo premiered the work earlier this month and the mountain gig will be their second time at it.

Meyer wrote the work expressly for himself and Bell, so it’s customized, so to speak, for their unique talents. In a musical world where much of the material is at least a century-old, that’s a rare occurrence.
